Transparency alternatives to Prolific
Other User research and testing vendors we measure, sorted by how much we found at them and not at Prolific. This is a comparison of disclosure, not of features or fitness.
12 shown of 34 that differ from Prolific on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Prolific has 10 gaps in what we could measure: Data processing agreement, Subprocessor list, Data location stated, Status page with history, Certifications named, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116), Notice before subprocessors change, Named privacy contact. The column “Found there, not found at Prolific” is the one that closes them.

Only criteria we could measure for both are counted. Where we could measure one and not the other, the row is silent: that would be a statement about our measurement, not about either vendor. Every single result with its source is on the two profiles.
